we use a lot of 878 and 1803 routers for G.SHDSL connections on two or four wires. One of our carriers uses (Lucent) DSLAMs which are incompatible with Cisco shdsl firmwares newer than 3.0.5.
How can I determine latest IOS versions with shdsl firmware 3.0.5?
( Table 5 on https://www.cisco.com/en/US/prod/collateral/routers/ps221/prod_bulletin0900aecd801d5c4c.html is not very up to date, I guess)
Can I run current IOS versions and load the "old" DSL firmware seperately like one can do on ADSL routers? If so, where can I download the firmware binaries and how do I have to load them into the router?
Thanks a lot in advance for any hint.
